I'm selling this monitor because I no longer need it. I was using it until recently. I believe it's a 27-inch monitor. Please check the model number listed. There is no original box, so I will pack it in a separate cardboard box. The only included accessory is the power cord. The I-O DATA LCD-AH271EDW is a high-performance monitor that consumes 33W of power and supports 100V, 50/60Hz. - Brand: I-O DATA - Model Name: LCD-AH271EDW - Power Consumption: 33W - Voltage: 100V - Frequency: 50/60Hz Thank you for looking.
